The Academy Award for sound editing ended in a tie this year, marking the third time in history a hung jury has awarded two gold statues.

Mark Wahlberg and Ted, the animated teddy bear brought to life by Oscar host Seth MacFarlane this summer, announced the surprise to the crowd Sunday evening, drawing a groan from the audience.

“No B.S. We have a tie,” Wahlberg told the audience as he announced the first winner for the award: Zero Dark Thirty. The James Bond flick Skyfall also earned the award.

Ties are a once-in-a-generation kind of thing. The Academy’s practice is that if one contender leads another by fewer than three votes, the Oscar will be awarded to both. So when has it happened in the past?
